Inventor: TERASHI HIROTO
IPC: H02M3/28
Filed: 1994-05-31
Abstract: PURPOSE:To reduce the size of smoothening capacitors at input side and output side at the same time. CONSTITUTION:Partial resonance converters 11 and 31 are connected in series to a load 41. An oscillator 42 for supplying drive signals of duty D=0.44 to 0.55 to a first FET 3 is provided. Also, an inverter 43 for supplying drive signals to a first FET 23 after inverting an output from the oscillator 42 is provided. Therefore, an input current Ii for the whole of a power supply equipment is an added current of input currents I1 and I2 of converters 11 and 31. Because of this, ripple components of the input current Ii are reduced. Also, voltages VL1 and VL2 applied to choke coils 10 and 30 have a waveform equal to the output voltage Vo without ripple components.

Title: Pickup cartridge
Inventor: TOMINARI NOBORU
IPC: H04R1/16
Filed: 1978-09-29
Abstract: PURPOSE:To make it possible to replace the stylus of a MC type cartridge, by combining two cantilevers together. CONSTITUTION:When stylus 13 traces on record 20, sound vibrations picked up are transferred to cantilever 11 and stylus 9 in touch with it picks up the sound vibrations and then transmits them to cantilever 8. Those vibrations vibrate armature 6 in a magnetic field and an output is extracted from a moving coil. As for a MC type pickup cartridge constituted in this way, stylus 13 wears while stylus 19 staying on lever 20 never wears. Here, stylus 13 is fitted to lever 11 fixed to detachable holding member 12. Therefore, stylus 13 can easily be replaced in one together with holding member 12 and lever 11.

IPC: G01F3/22
Filed: 1985-05-31
Abstract: PURPOSE:To attain to miniaturize a valve mechanism, by constituting a valve mechanism performing the change-over of a gas flow passage so that the valve reciprocating on the valve seat of a distributor is instantaneously operated between both poles of the stroke of said valve. CONSTITUTION:Because a valve arm 23 and a valve 11 are connected through a leaf spring 26, when the valve arm 23 is revolved, the valve 11 is held in a state stationary at the original position while repulsive force is accumulated in the leaf spring 26 by the compressive deformation of said spring 26. When the leaf spring connection point at the leading end of the valve arm 23 exceeds the upper dead point position, the force accumulated in the leaf spring 26 by the compression thereof is released at a stroke and the valve 11 performs the instantaneous change-over operation from one pole position of a reciprocal stroke toward the other pole position thereof at the timing point of time in the change-over of the flow passage thereof. By repeating this process, the metering of gas is performed.

Title: Clock phase difference holding system
Inventor: SANO HIROYUKI
IPC: H04Q11/04
Filed: 1987-05-15
Abstract: PURPOSE:To keep a phase difference constant by generating a frequency f2 being a plural number of multiple of two clocks in the same frequency f1 having a phase difference and using a control signal generated through the detection of the phase difference so as to retard one clock of the frequency f1 over plural number of stages. CONSTITUTION:Two clocks CLK1, CLK2 having a frequency f1 and a phase difference are inputted to a phase comparison means 20. A clock generating means 10 generates a clock CLK3 whose frequency is f2 being a plural number of multiple to the frequency f1 and the inputs the result to the phase comparison means 20. The phase difference at the trailing of the clocks CLK1, CLK2 is compared 20 with that of the clock CLK3, and the result of detection is inputted to a control signal generating means 50 to output a control signal 10 from a selection means 40. The CLK2 is retared over plural number of stages by a retarding means 30 and inputted to a selecting means 40. The control signal 10 applies control so that the phase difference between the CLK1 and CLK2 and the sum of delays to be selected 40 are constant and outputs to terminals 10, 11. Thus, even if the phase difference between the CLK1 and CLK2 is changed, a prescribed phase difference is kept easily.

Title: Phase shift circuit
Inventor: KOKURIYOU KENJI
IPC: H03H11/20
Filed: 1983-06-30
Abstract: PURPOSE:To decrease the output level fluctuation and the number of components by connecting resonance circuits having different resonance frequencies respectively in cascade by making a control voltage of a varactor diode different. CONSTITUTION:Since the varactor diodes D1-D3 each have different resistance values of resistors R1-R3, they are set to different capacitances from each other and the resonance circuits F1-F3 take respectively different frequencies f1-f3. Thus, the overall frequency characteristic is made flat in a frequency band of nearly F1-f3 and the output fluctuation due to the defference in the input frequency is less. Further, the phase variable width with respect to the frequency is larger by the share of increase in the resonance circuit number and the linearity of the phase change is improved. Further, the frequency versus amplitude and the frequency versus phase characteristic curves are shifted by changing a control voltage Vc.
